Grounding structure of connector

Abstract

A grounding structure of a thin-typed connector includes an insulating main body, a first terminal group, a second terminal group, a shielding case and a grounding sheet. The insulating main body is disposed with a base portion and a tongue plate. The grounding sheet is fixed between the base portion and the tongue plate. The first and the second terminal groups are accommodated in the insulating main body which is accommodated in the shielding case. The grounding sheet is formed to a shielding plate and a first flat plate from a metal sheet. The shielding plate is located on the tongue plate. The first flat plate is located on the base portion. Two sides of the main body of the grounding sheet bend and extend outwards, and are respectively disposed with a snapping portion. The snapping portions are configured to mutually snap and fix with a docking connector.

What is claimed is: 
     
         1 . A grounding structure of a connector, comprising:
 a shielding case;   an insulating main body accommodated in the shielding case;   a first terminal group accommodated in the insulating main body;   a second terminal group accommodated in the insulating main body; and   a grounding sheet having a main body and at least two snapping portions, two sides of the main body bending and extending outwards, the snapping portions being respectively disposed at each of the two sides of the main body, wherein the snapping portions are configured to mutually snap and fix with a docking connector.   
     
     
         2 . The grounding structure of the connector of  claim 1 , wherein the insulating main body is disposed with a base portion and a tongue plate, the grounding sheet is formed to a shielding plate and at least one first flat plate from a metal sheet through cutting and bending, the shielding plate is at least partially located on the tongue plate, the first flat plate is at least partially located on the base portion. 
     
     
         3 . The grounding structure of the connector of  claim 2 , wherein two sides of the shielding plate partially bend and extend outwards to respectively form the snapping portions. 
     
     
         4 . The grounding structure of the connector of  claim 2 , wherein the shielding plate and the first flat plate are located on different planes of the insulating main body. 
     
     
         5 . The grounding structure of the connector of  claim 2 , wherein the grounding sheet comprises:
 a contact piece disposed at an outward extension of the first flat plate, the contact piece is at least partially exposed outside the base portion.   
     
     
         6 . The grounding structure of the connector of  claim 2 , wherein the first flat plate partially bends downwards and extends and then bends inwards to form the snapping portion at an end after extending parallel with the shielding plate for an appropriate distance. 
     
     
         7 . The grounding structure of the connector of  claim 6 , wherein each of the snapping portions bends inwards and barbs to form a hook. 
     
     
         8 . The grounding structure of the connector of  claim 1 , further comprising:
 a shielding cover covering the shielding case.   
     
     
         9 . The grounding structure of the connector of  claim 1 , wherein the first terminal group comprises:
 a first fixing portion; and   a plurality of first terminals assembled on the first fixing portion.   
     
     
         10 . The grounding structure of the connector of  claim 1 , wherein the second terminal group comprises:
 a second fixing portion; and   a plurality of second terminals assembled on the second fixing portion.
